This is my daughters purebred shorthorn steer. When we got him he weighed 580#, 32 days later I weighed him again, he weighed 704#. If I'm figuring it right he is gaining 3.84# a day. he is eating 20# premixed feed a day and depth charge. He gets a couple lbs of grass hay daily as well and free choice mineral lick. I need to cut him back k as our weigh in for 4-h is end of January. I'm wanting him around 800-850 at weigh in so I won't have to worry about him making the required rate of gain to get on the auction. What do you guys think of him and any suggestions as fas as what to feed him now.
I don't have all of the details, but I am going to tell you the basic formula and variables that I use when we get a calf in.
I always assume about 50 pounds of shrink on a feeder size steer. So in your case, the 580# would have converted to an actual 630# weight. Re-calculate the ADG, and it comes up to 2.31/day......which is still really good considering the acclimation period, the change in feed, and the fact that you are just getting him wound up!
Now I round that number up, so in your case I would use 2.5/day. If you are 75 days from weigh in, that means he will add about 185 pounds. That will put your steer at about 890#, and he will shrink some on the trailer ride to weigh in.
What this formula gets ME is a weight that I consider to be manageable in terms of shrinking him back for weigh in without running the risk of not feeding him enough and having him turn into a big tall race horse looking thing.
I believe (this is just MY opinion) that how a steer is fed between 500 and 900 pounds will determine what he ends up being in the end.
I also agree with Mark's advice about the "burn method".
Nice steer, and you are doing a great job. Getting a weight on him every month or so is the best way to know!
